<P>PROBLEM TO BE SOLVED: To provide a welding torch in which the chips of a wire accumulated in the interior are easily removable. <P>SOLUTION: The torch includes: a guide body 500 having a first wire inserting hole 510; a power supply tip 600 having a second wire inserting hole 640, the diameter of which is contractible elastically; a cylindrical slide member 700 which is slidable in the axial direction to the guide body 500; an elastic member 730 for energizing the slide member 700 in the direction of the base end of the guide body 500; and cylindrical nozzle 250. The slide member 700 is a welding torch which makes the diameter of the second wire inserting hole 640 contract by being brought into contact elastically with the power supply tip 600 and, when the pressure of gas which is fed into through a tip body 300 is not lower than a prescribed pressure, the slide body 700 is configured so as to relatively move in the direction of the point against the guide body 500 or the power supply tip 600 by opposing energizing force by the elastic member 730. <P>COPYRIGHT: (C)2013,JPO&INPIT |
